I'm not usually this lucky, through my home warranty company, I was assigned Lee Collins Air. Over the last few years, my older A/C unit has been starved for attention. Since my initial experience with Lee Collins, I have been impressed. Each time that I have called for service, they have been professional, kind, empathetic and have arrived when they said that they would. I trust them so much that I have given them my door code to service my A/C in my absence.
I strongly recommend this company, because of their work ethic and reliability.
(They even came out on New Years Eve, on a last minute request because my unit had stopped heating.)
